Initial value problems-a system of ordinary differential equations and corresponding initial conditions-can be used to describe many physical phenomena including those arise in classical mechanics. We have developed an approach to solve phy...
First-passage-time statistics of active Brownian particles: A perturbative approach [0.03%]

We study the first-passage-time (FPT) properties of active Brownian particles to reach an absorbing wall in two dimensions. Employing a perturbation approach, we obtain exact analytical predictions for the survival and FPT distributions for...
Molecular dynamics simulation of channel-size dependence of the force around a liquid-vapor-solid contact line region [0.03%]

Molecular dynamics was used to evaluate the channel size dependence of force acting near a liquid-vapor-solid contact line. The shear stress distribution acting on the solid wall surface was calculated using the spatial distribution of the ...

The fragility of financial systems was starkly demonstrated in early 2023 through a cascade of major bank failures in the United States, including the second, third, and fourth largest collapses in U.S. history. The highly interdependent fi...
Mutual information for a particle pair and its application to diagnose chaos in curved spacetime [0.03%]
粒子对的互信息及其在诊断曲时空混沌中的应用

We propose the concept of mutual information for particle pair (MIPP) in curved spacetime, and show that MIPP has potential to be a proper chaos indicator. We tested this method in the Schwarzschild and Kerr spacetime and compared it with t...

Liquid-liquid phase separation (LLPS) in a confining environment is believed to play an important role in cell biology. At least in some cases, this form of LLPS involves free energy consumption, which could lead to breakdown of the fundame...
Phase-field study of the effective fracture energy increase during dynamic crack propagation in disordered heterogeneous materials [0.03%]

The propagation of a three-dimensional crack in a heterogeneous material is studied using a phase-field model. It is shown that, in the case of randomly distributed inclusions of soft material in a matrix, the nature of the distribution has...

In this work a viscoelastic model that couples enveloping cell layer velocities and tensions is built including the geometric corrections on the sphere surface, showing that stress anisotropy increases in the layer as a function of the pola...
Viscous liquid dynamics modeled as random walks within overlapping hyperspheres [0.03%]

The hypersphere model is a simple one-parameter model of the potential-energy landscape of viscous liquids, which is defined as a percolating system of same-radius hyperspheres randomly distributed in R^{3N}, in which N is the number of par...

Physical and chemical factors limit the maximum amount of energy that a living cell can expend per unit time. As the cell ages, its capacity to produce energy gradually decreases, ultimately vanishing when it reaches its natural life limit....
